Why Accuracy Matters
In cities, where crowds gather, the difference between accurate vertical gunfire location and a false-positive system can literally be measured in lives saved. Accurate vertical gunfire location can identify the precise floor, room, or open-air coordinates within seconds—eliminating the deadly delays caused by vague “building alarms.” Systems proven under DHS SAFETY Act testing achieve >99.9 % detection with near-zero false alarms from slamming doors or fireworks, ensuring first responders in cities receive exact shooter location and weapon type intelligence the moment the first round is fired.

Not sure where to begin? The DHS SAFETY Act website maintains an up-to-date list of every approved vertical gunfire location technology, complete with coverage scope (indoor, outdoor, vertical) and real-world deployment examples. Filter specifically for systems proven in climates and densities matching cities to make informed decisions quickly.
How to choose the right vertical gunfire location for cities
Total cost of ownership in cities hinges on false-alarm performance. Even one unnecessary SWAT rollout can exceed $100,000. Choose vertical gunfire location solutions with documented false-alarm rates below 1 per 10,000 sensor-days (verified by DHS testing) to protect both lives and the emergency-response budget.
Other considerations for vertical gunfire location in cities
Beyond accuracy, city decision-makers must consider liability exposure. Only DHS SAFETY Act-covered vertical gunfire location provides statutory caps or elimination of third-party claims following an attack. Without this protection, even the most accurate system leaves venues like schools and businesses vulnerable to lawsuits claiming the technology “should have done more.”
